5.87× 10⁹

Step-by-step explanation:

We need to find the value of 6.27 × 10⁷ + 5.81 × 10⁹.

It can be done as follows:

6.27 × 10⁷ + 5.81 × 10⁹ = (6.27 × 10⁷ × 10² × 10⁻²+ 5.81 × 10⁹)

=(6.27 × 10⁹ × 10⁻²+ 5.81 × 10⁹)

= (0.0627× 10⁹ + 5.81 × 10⁹)

= 5.87× 10⁹

So, the required answer is 5.87× 10⁹.

i'm using the rule log(x/y) = log(x) - log(y)
